Before even having a chance to catch his breath, Tony felt Natasha's strong grip bind his hands with a strip of silk she ripped off of the bedspread. He was sprawled out on his back on the bed and Natasha sat perched on his chest in order to prevent him from moving.

"What the..." Tony said in disbelief as he felt her tie him to the head board swiftly and skillfully. He felt the blood rushing straight to his cock from the unfamiliar yet arousing sensation of being bound by a sultry woman. The devilish yet lustful gleam in Natasha's eyes remained in tact and contributed to Tony's arousal. She finally secured the knot.

"Ready to go for a ride, cowboy?" she cooed in his ear, while pumping her hand up and down on his massive erection. Her tits looked so round and firm and he wanted to just grab them, but the restraints caused him to struggle. He gritted his teeth in frustration and primal desire; he wanted to be back in control. Natasha pushed her knee down harder on his chest.

"No, no, no... Where do you think you're going?" she teased, grasping Tony's cock more firmly than before. He grunted as he thrust upward into her hand, desperately trying to seek release. She abruptly let go, and Tony slammed his head against the pillow.

"What's wrong, Mr. Stark? You scared of a dominant woman?"

"Natasha, I think you've teased me long enough... Restraints? Really? We both know that's not going to stop you from riding the fuck out of me in about 5 sec-" Tony was cut off by Natasha lowering her dripping wet pussy onto his solid rod. She threw her head back with pleasure and began to ride him hard.

"Oh my fucking God, YES!" she screamed out, bouncing up and down hard on his entire length. She could feel him hitting her g-spot as she angled herself to achieve the perfect position.

"Oh my god, harder baby... Ride me harder!" Tony grunted as he stared at the beautiful woman who was bouncing and gyrating on his cock. Although his hands were bound, Tony was thrusting upward full force, feeling the wet heat slam on his entire cock. He watched as Natasha's knuckles turned white from gripping the silk sheets with ecstasy, her eyes squeezed shut as she rode harder and harder to achieve orgasm.

"Fuck, Natasha... You are so fucking HOT..." Tony growled as he could tell his partner was about to reach her climax.

"Oh my.. Oh my god...AHH!" Natasha cried out as she felt her pussy tighten around Tony's cock. She collapsed on top of him, when she suddenly heard a rip. She opened her eyes and saw that Tony had ripped himself free from her makeshift restraints, and within a matter of milliseconds, Tony flipped her over onto her back and had her pinned to the bed.

"I think it's time that I end this the way it should be... On top," Tony whispered against her ear, causing her to shiver. "The night isn't over yet."
